DRAFT-EQUALIZER.

`ZE'ECIFICATION forming part of Letters Patent No. 388,353, dated August21, 1888.

Application filed December 9, 1887. Serial No. 257,368. (No model.)

T0 all whom, it may cal/Learn.:

Beit known that i, MAT'r FRAMBACH, a citizen of the United States ofAmerica, residing at Cherokee, in the county of Cherokee and State ofIowa, have invented a new and useful Dralt-Equalizer, of which thefollowing is a specification.

Myinvention has relation toimprovements in means for equaliziug thedraft, of that character wherein levers of different lengths areutilized in a common line of draft With the weight or resistance, andthe object is to construct a four-horse draft-equalizer in which threehorses are hitchcd to walk abreast on one side ot' the tongue and asingle animal on the other side. The device is particularly apph'cableto harvesters to permit the single animal to travel on the side next thestanding grain; but the device may be used Wherever similarcircnmstances of restriction of space occnr.

l have fully illustrated niyimprovements in the aecompanyingdrawings,wherein-- Figure l is a top plan view of the device. Fig. 2 is a view ofthe evener drawn at an augle, the main lever and doubletree being brokenoff to better show the connection.

Reference being had to the drawings, vA designatcs the tongue, which mayhe of any ot' the nsual and approved constructions. On the tongue ispivotally attached the lever B which has a keeper, 1, arranged over it,as shown, and through which the holt 2 passes which holds the lever tothe tongue. To

, strengthen the long arm of the lever B, a plate,

3, is arrauged in line therewith on the upper side, and has one endrigidly secured to the lever, as at 4, and the otherend is held by thebolt 2.

On the long cud of the lever is coupled a doubletree, O, which ispreferably mounted on the face ot' the lever and held by a clevis, 5,and pivot-bolt 6, substantially as shown. The bow of the clevis isarranged to extend back- Ward to afford convenient means to which thecord or chain may be connected. The doubletree O is coupled to the leverin the proportion of two to one as compared With the short arm thcreof.Singletrees 7 are connected to the doubletree O, as usual.

D designates the evener, which consists of a substantial lever havingone end pivoted to the end of the short arm of the lever, as at 8, andon the other and inner end has pivotal connection with the doubletree E,which has singletrees 7, connected as shown. The evener D is of suchlength as to permit the doubletree E to be connected thereto to throwonehalf on the opposite side of the tongue, and thus make three horsestravel on one side and but one on the other.

On the rear part of the tongue is mounted a sheave, 9, within a propercasing, 10, and over the sheave is arranged a cord or chain, 11, havingone end attached to the end of the long arm of the lever and the otherend attached to the inner end of the evener, substantially as shown. Bymeans ot' the cord and sheave connection it will be seen that the coupleof two to one directly with theleveris overcome, and the ultimate resultof the connection is an equal draft on each side of the tongue or anequivalency ot' leveragcs.

Vhat I claim is- In a four-horse draft-equalizcr, the combination, withthe tongue A, of the lever B, pivotally mounted on the tongue with thearms two to one and provided with the strengthening-plate 3, the evenerD, having its outer end pivoted to the end of the short arm of thelever, the douhletrce E, pivoted to the inner or free end of the evenerD, the sheave 9, mounted on the rear end of the tongue, the doubletreeO, pivoted to the end of the long arm of the lever, and the cord ll,arranged on the sheave and having one end connected to the center ot'the doubletree on the evener and the other end connected to the clevisof the doubletree on the end of the long arm of the lever.

In Witness whereof I have hereunto set my hand in the presence oftwoattesting witnesses.

MATT FRAMBAOH.
